ONE Gas, Inc. reported higher profitability for the three and six months ended June 30, 2026, despite lower revenue. Second‑quarter revenue was $411.6 million versus $423.7 million a year earlier, while net income increased to $46.8 million, or $0.74 diluted EPS, from $32.0 million, or $0.53.
For the first half, revenue was $1,243.3 million compared with $1,359.0 million, but net income rose to $175.5 million and diluted EPS to $2.78 from $151.5 million and $2.51. Operating income improved to $272.2 million, driven mainly by new rates and customer growth, partly offset by higher employee and service costs and weaker weather‑driven volumes.
The company serves about 2.3 million regulated natural‑gas customers in Oklahoma, Kansas, and Texas. It invested $357.9 million year‑to‑date in capital and asset removal and expects about $800 million for 2026, funded largely from operating cash flow, commercial paper, and a $1.5 billion unused credit facility.
ONE Gas, Inc. reported significantly stronger results for the quarter and six months ended June 30, 2026 and raised its 2026 adjusted earnings expectations to the upper half of its prior guidance ranges of $306–$314 million of adjusted net income and $4.83–$4.95 adjusted diluted EPS. Second‑quarter 2026 adjusted net income was $52.1 million, or $0.82 per diluted share, versus $32.7 million, or $0.54, a year earlier; GAAP net income was $46.8 million, or $0.74 per diluted share, up from $32.0 million, or $0.53. Year‑to‑date adjusted net income rose to $185.5 million, or $2.94 per diluted share, compared with $152.8 million, or $2.53, in 2025.
Operating income increased to $82.7 million in the quarter, driven mainly by $16.4 million of new rate revenue and customer growth, partly offset by higher employee and service costs. Warmer‑than‑normal weather reduced usage, but the impact was mitigated by weather normalization mechanisms. Excluding KGSS‑I securitized bonds, net interest expense declined by $3.8 million for the quarter and $6.7 million year‑to‑date, aided by lower‑rate commercial paper and Texas House Bill 4384. Capital expenditures and asset removal costs were $188.3 million for the quarter and are expected to total about $800 million in 2026, including roughly $230 million for system extensions. The board declared a quarterly dividend of $0.68 per share ($2.72 annualized), payable August 31, 2026, to shareholders of record on August 17, 2026. Regulatory filings in Kansas, Oklahoma and Texas seek or implement additional rate increases and customer credits tied to infrastructure and performance‑based mechanisms.
ONE Gas, Inc. reports that its Board of Directors approved and made effective Amended and Restated By-laws on August 4, 2026. The update allows the chair of the Board, if so appointed, to serve as a full member of one or more standing or special committees, with the same voting, quorum and other rights as other committee members.
Unless the Board determines otherwise, the chair may also serve as an ex-officio participant on all standing committees and will chair any executive committee. In the ex-officio role, the chair may attend and participate in meetings but has no voting rights, is not counted for quorum, and is not treated as a committee member for by-law, legal or stock exchange composition and independence requirements. The changes specify that the chair’s participation must not cause any committee to fail to meet applicable law, regulation or listing standards. The full Amended and Restated By-laws are provided as an exhibit and incorporated by reference.
